Patent CA-2725417-A1 (CA)
Inventor: GERASCHENKO EDUARD ARKADJEVICH
IPC: B62D55/104
Filed: 2009-04-28
Abstract: The invention relates to transport engineering, in particular to the suspension systems for caterpillar drives. The levered centerpoint suspension of a caterpillar drive comprises a pendulum arm, which is coupled to a frame via an elastic element, and a pivot pin geometrically coinciding with the rotational axis of the shaft of the drive sprocket wheels (chain gears). A  balancing lever provided with track idlers and/or track wheels and/or track slide guides is connected to the pendulum arm in such a way that it swingable thereon. In the first variant the sprocket shaft axis is secured between two frame brackets. The shaft with the sprocket wheels rotates about said axis and the pendulum arm socket is put onto the middle part of the shaft as onto a pivot pin. In the second variant, the sprocket shaft axis is secured between two frame brackets. The socket of an U-shaped fork-like pendulum arm swings on said axis. The shaft with the sprocket wheels rotates about the middle part of the socket as about an axis. According to the third variant, the pendulum arm is in the form of a fork. The balancing lever is H-shaped and comprises two longitudinal girders interconnected by means of a crossbar. The balancing lever is disposed between the pendulum arm blades and is connected to said pendulum arm as to swing on a transverse axis. The invention makes it possible to increase the tension force of a track.

Abstract: Heat exchangers can be utilised in thermo-acoustic engines to facilitate through acoustic oscillations electrical power generation via linear alternators and/or cooling effects. Provision of a heat exchanger arrangement (31) which can be associated with a traditional open flame stove utilised in third world countries would be advantageous. However, such heat exchanger arrangements must be lightweight and robust to withstand operational use. By creating a heat exchanger arrangement formed from plates having apertures which develop a folded conduit to act as a resonance tube of appropriate length it is possible to more easily accommodate thermo-acoustic electrical power generation and cooling effects in a traditional stove configuration.

Abstract: Un routeur local stocke une carte de distribution de contenu qui spécifie une pluralité de groupes de multidiffusion autorisés. Le routeur local reçoit des communications de dispositifs utilisateur sur un côté réseau daccès du routeur local. Ces communications reçues identifient les groupes de multidiffusion pour lesquels les dispositifs utilisateur désirent recevoir des données. Le routeur local détermine si ces groupes de multidiffusion identifiés sont des groupes de multidiffusion autorisés spécifiés par la carte de distribution de contenu stockée. Pour les groupes de multidiffusion dont lautorisation a été établie, le routeur local envoie des communications à travers une interface côté réseau demandant une adhésion à ces groupes de multidiffusion. Le routeur local peut alors recevoir des données pour ces groupes de multidiffusion et acheminer ces données à des dispositifs utilisateur.

De manière caractéristique, au mélange réactionnel issu directement de la première étape de transestérification, on ajoute une solution aqueuse pour obtenir un mélange réactionnel comprenant notamment des esters d'acides gras hydroxylés et du glycérol. Ce mélange réactionnel est soumis à une étape de séparation permettant d'obtenir une phase moins dense composée majoritairement d'esters gras et une phase plus dense composée majoritairement de glycérol, et d'eau et de savons d'acides gras. La deuxième étape de transestérification est effectuée sur la phase moins dense additionnée dudit alcool léger et dudit catalyseur basique.

Title: Methods and systems for treatment and/or diagnosis
Inventor: VON MALTZAHN GEOFFREY A
IPC: A61K47/48
Filed: 2010-03-02
Abstract: The invention relates to methods and systems that can be used for treatment and/or diagnosis. In one aspect, the present invention involves systems and methods for activating a biological cascade in a subject, and administering, to the subject, a composition or a component comprising an agent able to bind a product of a biological cascade or otherwise interact with the biological cascade. The biological cascade may be, for example, a coagulation cascade, a complement cascade, an inflammation cascade, or the like. In some cases, the concentration of a protein, the metabolic demand for a substrate, or the like may be increased as a result of activation of the biological cascade. As a specific non-limiting example, in one set of embodiments, the biological cascade may be a coagulation cascade and the composition administered to the subject may include a fibrin-binding peptide and an antitumor species. By activating the biological cascade, e.g., with an activation composition or by applying energy, coagulation may be induced in a tumor, which the antitumor species may associate with due to an increase in fibrin caused by the coagulation cascade. In addition, in certain aspects, the present invention involves systems and methods for changing tissue from a first state to a second state, for instance, with a first composition comprising nanoparticles. The second composition may be more responsive to the tissue in the second state than in the first state in some cases. In still other aspects, the present invention is generally directed to systems and methods for making such compositions, systems and methods for promoting such compositions, kits involving such compositions, or the like.

Title: Child car seat
Inventor: HUTCHINSON JAMES M F
IPC: B60N2/90
Filed: 2008-09-09
Abstract: A latching mechanism for a car seat that is mountable on a separable base member provides a positive locking of the car seat to the base member. The latch mechanism has a member that is positioned in the seat portion of the car seat to pivot upwardly when the latch mechanism is disengaged. The seating of a child on the seat portion requires the latch mechanism to be retracted into the seat portion, which corresponds to the locking of the latch mechanism. The latch mechanism includes four helical spools rotated by the pivotal movement of the latch lever to cause linear movement of the locking pins into engagement with the base member. A latch indicator has a pre-latch sensor that indicates proper positioning of the seat member and a latch sensor that indicates an engagement of the locking pins. An indicator light illuminates when the seat member is properly latched.

Title: Novel architecture of a compensator for power factors and harmonics for a power distribution system
Inventor: THOMAS PHILIPPE
IPC: H02M1/42
Filed: 2010-07-08
Abstract: The subject of the invention is a rectifier system for a primary AC  electrical power distribution system comprising a PFC circuit connected onto the primary distribution system which delivers a DC power supply and means for storing electrical energy connected to the outputs of the PFC via a switching circuit. This circuit is controlled in such a manner as to effect either the discharge of the electrical energy stored in the storage means onto the DC power supply line, or the charging of the storage means by the DC power supply line. A first control circuit determines the state of operation of the switching circuit by comparing the value of the voltage on the power supply line with a first reference voltage. A second control circuit regulates the power delivered by the PFC over the power supply line by comparing the voltage present at the output of the storage means with a second reference voltage. The two control circuits are crossed. The system according to the invention advantageously allows load demands to be handled without causing interference to the primary distribution system.
